Agent Memory Is Just a Database You Forgot to Index

In my previous article, I explored why personas still matter when working with AI agents. Distinct perspectives shape output in ways that raw context alone cannot replicate. But I also raised a limitation that I want to address head-on: every fresh context window starts from zero. The persona needs to rebuild its understanding of your codebase from scratch, every single time. This is not just an inconvenience. It is a structural problem. If every session begins with a blank slate, your agents spend tokens re-discovering things they already knew. They scan files they have already read.
